COVID-19 patients Possess Resistance for Half a Year, Research finds

People previously infected with Covid-19 are "highly unlikely" to contract the illness again for at least six months, a study at Oxford University has discovered.

"By studying these multiple compartments of adaptive immunity in an integrated manner, we observed that each component of SARS-CoV-2 immune memory exhibited distinct kinetics", the researchers wrote in the study.

During the study, 89 of 11,052 staff without antibodies developed a new infection with symptoms, while none of the 1,246 staff with antibodies developed a symptomatic infection.

The researchers studied all three diseases was to determine why Covid-19 has spread more rapidly than the earlier diseases.

He explained after following individuals for six months that the researchers were excited to talk about their outcomes.

The researchers then followed whether staff who had been infected before had the same number of new Covid-19 infections as those who had not been infected before.

Antibodies were undetectable after 50 days in individuals who "develop modest neutralizing antibody titres after infection", while those patients who had more severe symptoms could continue to produce antibodies up to 60 days after infection, that study found. There were no significant correlations between mumps titers and disease severity in the comparison group, between mumps titers and age in the MMR II group, or between severity and measles or rubella titers in either group.

4 terrorists killed, 1 policeman injured at Jammu's Nagrota toll plaza
The gun battle started at around 5 am near the toll plaza in the Ban area of Nagrota on the Jammu-Srinagar highway on Thursday. Many tunnels being used by the infiltrators have been detected by the Border Security Force in the last few years.

Dr Katie Jeffery, director of infection prevention and control for Oxford University Hospitals said: "This is an exciting finding, indicating that infection with the virus provides at least short-term protection from reinfection - this news comes in the same month as other encouraging news about Covid-19 vaccines".

Within the MMR II group, mumps titers of 134 to 300 AU/ml (n=8) were only found in those who were functionally immune or asymptomatic. Levels of less than 134 AU/ml were found in those with mild symptoms, and those with moderate symptoms all had titers belt 75 AU/ml.

The report used meta-analysis to assess 98 studies on Covid-19, SARS and MERS.

The figures also found there were "substantial differences" in COVID-19 infection rates across England, with increases in London, the east of England and the South East. And he considered that this finding makes "expect longer periods of protection" when a vaccine is available. "The majority of children get their first MMR vaccination around 12 to 15 months of age and a second one from 4 to 6 years of age".

As record-breaking numbers of COVID-19 infections continue to surge across the USA, scientists at St. Jude Children's Research Hospital say they've found a possible COVID-19 treatment, and suggest that the "process driving life-threatening inflammation, lung damage and organ failure in patients with COVID-19, sepsis and other inflammatory disorders" could possibly be treated using existing drugs.

What if we don't find a vaccine for Covid-19?
